Argon Audio FENRIS A55
A feature packed sound wonder
With ARC for TV audio, Bluetooth 5.0, phono input for turntables, subwoofer output and then still both an analog and digital input to spare, FENRIS handle virtually all sources you could dream of throwing at them. FENRIS also automatically switch input between the sources you have connected, so in day-to-day use you rarely even need to grab the included remote control. Simply connect your favorite sources, sit back, and enjoy the fantastic sound quality.
Since the digital amplifier in FENRIS has four channels, we were able to assign each driver separate amplifier channels. Doing this, we solve one of the classic challenges of traditional speakers: ensuring that the transition between the treble (the high tones) and the woofer (the deeper tones) is smooth and sounds natural. The technology we use here is called an 'active crossover' and is generally much more accurate than a classic, 'passive' crossover. But wait, there’s more! Because both the amplifier and the drivers in these speakers are our own design, we have optimized them to work perfectly together and tuned everything using advanced DSP. What we’re saying is: our skilled engineers have spent countless days tweaking everything to make sure that your FENRIS speakers perform at their very best. We’d say that they can easily run laps around most classic speakers that cost many times more. The good part is, that you don’t have to worry about all this technical stuff. Just plug them in and press play!
In Argon Audio we firmly believe that you also listen with your eyes. That’s why we have designed FENRIS to look the way they sound: impressive and yet elegantly detailed. The front grille is magnetically attached, meaning that even if you do decide to take it off to see the stylish aluminum trim rings, you don’t have to worry about unsightly holes or visible screws on your speaker. FENRIS is available in multiple good looking finishes.
"A grown Fenris! Like the other models in the same range, the Argon Audio Fenris A55 has a fresh and open sound, leaving no tonal area untouched. This makes listening easy and invites you to play louder than just background music. Which is always a good thing. After all, that's what music and electronics are made for."
"The Fenris A55 performs exceptionally well with a variety of music genres, from rock and house to dance music, as well as singer/songwriter tunes like those of Leonard Cohen. The crossover is seamless and tonal ranges are well-balanced. Argon Audio has done an excellent job of integrating many features with high-quality sound at a low price point. The sound quality is above expectations for its price range."
"With the Argon Audio Fenris A55, you can enjoy excellent sound quality at a very reasonable price. The speaker set provides versatile connection options, ranging from your TV to your record player, making it an excellent choice as the centerpiece of a low-budget hi-fi system."
"As for their practicality, they really are very versatile speakers. I really like the fact that they have HDMI ARC; in fact, it allows you to use them practically like a soundbar and thus greatly improve the TV’s sound more than any extremely expensive soundbar – I can assure you of this because it’s a matter of the physics of sound."

What do A4, A5, and A55 mean?

A4 has a 4" woofer (compact, ideal for bedrooms/desks/TVs).
A5 has a 5" woofer (fuller sound, medium rooms).
A55 is a floor-standing pair with 2 x 5" woofers, for living rooms and room-filling bass.

Yes. FENRIS speakers feature both a dedicated PHONO input and a standard AUX input, making them compatible with virtually any turntable - no additional equipment required.
Choose the correct input depending on your turntable:
Turntable without a built-in phono preamplifier (RIAA) → Connect it directly to the PHONO input.
Turntable with a built-in phono preamplifier (RIAA) → Set the turntable to RIAA ON (or LINE) and connect it to the AUX input.
Recommended settings for Argon Audio turntables
This flexibility makes FENRIS compatible with virtually any turntable, whether it has a built-in phono preamplifier or not.
Yes. FENRIS speakers feature a built-in phono preamp (RIAA), allowing you to connect a turntable directly to the PHONO input without needing additional equipment.
Recommended settings for Argon Audio turntables
TT-3 and TT SIGNATURE: Connect to the PHONO input.
TT MK2: For the best sound quality, we recommend setting the turntable to RIAA OFF and connecting it to the PHONO input, allowing the FENRIS built-in phono stage to handle the amplification.
TT-3 Plus, TT-4 MK2, TT-4 Special Edition, and TT AURORA: We recommend setting the turntable to RIAA ON and connecting it to the AUX input. The built-in phono preamplifier in these models has been carefully matched to the supplied cartridge for excellent sound quality and the simplest setup.
With FENRIS, nothing extra - connect your turntable straight to the PHONO input and you're set.
Yes. FENRIS speakers are an excellent alternative to a soundbar, delivering true stereo sound with a wider soundstage and more natural audio for movies, TV shows, music, and gaming.
Simply connect your TV using HDMI ARC, and the speakers will automatically turn on and off with your TV. You can also control the volume using your TV remote, giving you the same everyday convenience as a soundbar—combined with the superior sound quality of a dedicated stereo speaker system.
To ensure proper audio playback, set your TV's digital audio output to PCM (Stereo). FENRIS speakers are designed for two-channel audio and do not support Dolby Digital, DTS, or other surround sound formats. If your TV is set to output one of these formats, you may experience no sound or other audio issues.
Yes. FENRIS speakers feature dedicated PRE OUT outputs, making it easy to add an active subwoofer for deeper, more powerful bass and an even more immersive listening experience.
For the simplest setup, we recommend the FENRIS Subwoofer Connect Kit, which includes everything you need to connect your speakers to a compatible subwoofer quickly and easily.
If you already have a subwoofer, simply connect it to one of the PRE OUT outputs using a standard RCA subwoofer cable.
FENRIS supports Bluetooth 5.0 with the SBC codec, making it easy to stream music wirelessly from your smartphone, tablet, or computer.
If you're looking for Wi-Fi streaming with AirPlay 2, Google Cast, or Spotify Connect, you have two great options:
If Bluetooth streaming is all you need, FENRIS provides a simple, reliable, and high-quality wireless solution.
At Argon Audio, active speakers are designed to deliver true hi-fi sound without the complexity of a traditional separates system.
Unlike passive speakers, which require an external amplifier, our active speakers have the amplifier built in. This allows you to connect sources such as a TV, turntable, smartphone, computer, or streamer directly to the speakers for a simple, space-saving setup.
Because the amplifier, drivers, crossover, and DSP (Digital Signal Processing) are all designed and tuned together, every component works in perfect harmony. The amplifier is precisely matched to the drivers, allowing us to optimize the sound, improve efficiency, and ensure consistent performance across the entire frequency range.
Depending on the model, Argon Audio active speakers also include features such as HDMI ARC, Bluetooth, built-in phono preamplifiers (RIAA), and Wi-Fi streaming, making them an ideal all-in-one solution for music, TV, gaming, and vinyl.
The main difference is that active speakers have a built-in amplifier, while passive speakers require an external amplifier to power them.
At Argon Audio, our FENRIS, FORTE, and STUDIE 3 series are active speakers. They combine the amplifier, drivers, crossover, and DSP (Digital Signal Processing) into a single, carefully tuned system. Because every component is designed to work together, the amplifier is perfectly matched to the drivers, resulting in optimized performance, excellent sound quality, and a simple plug-and-play setup.
Active speakers can be connected directly to sources such as TVs, turntables, smartphones, computers, streamers, and CD players, eliminating the need for a separate amplifier and reducing both clutter and setup time.
Our FORUS series consists of passive speakers. These speakers require an external amplifier or AV receiver to provide power and manage audio sources. This approach offers greater flexibility, allowing you to choose, upgrade, or replace your amplifier independently as your system evolves.
For stereo music systems, FORUS speakers pair perfectly with stereo amplifiers such as the SA1 MK2 or SA2. If you're planning to build a home cinema system with surround sound (5.1, 7.1, or more), you'll need a compatible AV receiver instead of a stereo amplifier.
Which should you choose?
If you're looking for the simplest, smartest all-in-one solution with exceptional sound quality and minimal setup, active speakers are the ideal choice. If you prefer maximum flexibility, enjoy upgrading individual components, or plan to build a surround sound home cinema system, passive speakers may be the better fit.
The main differences are size, bass performance, and output capability.
The FENRIS A4 and A5 are bookshelf speakers featuring a 2-way design with one woofer and one tweeter. The A5 uses a larger woofer, allowing it to deliver deeper bass and higher output than the A4.
The FENRIS A55 is a floorstanding speaker featuring two woofers and one tweeter. The additional woofer and larger cabinet help it produce deeper bass, greater dynamics, and higher volume levels, making it particularly well suited for larger rooms.
All three models offer the same connectivity and features. The best choice depends on your room size, available space, and how much bass and output you want.
No. Our active speaker systems are designed as dedicated stereo pairs, consisting of one left and one right speaker.
They do not support adding additional speakers for surround sound, multi-channel audio, or expanding the stereo setup. If you are looking for a simple and high-quality two-channel listening experience, active stereo speakers are an excellent choice.
As a general rule, we recommend placing your speakers 10–30 cm (4–12 inches) from the rear wall. This usually provides a good balance between bass performance, soundstage, and clarity.
Placing speakers closer to the wall will typically increase bass output, while moving them further into the room can improve imaging and reduce bass coloration.
The ideal distance depends on the speaker model, room acoustics, and your personal preferences. If possible, experiment with different positions to find the sound that works best in your room.
No. That's the whole point of active speakers - FENRIS, FORTE MK2, FORTE WIFI, and STUDIE 3 all have amplification built in, so you can connect your TV, turntable, phone, or computer directly with no separate amplifier required.
That means a smaller footprint, one less box to buy, and fewer cables to manage, without compromising on sound quality.
